'Even though Alex was a research animal, he was much more than that. This species of parrot generally lives to be 50-60 years old, so Alex was only middle-aged when he died. According to some reports I have read, it is possible that Alex might have succumbed to Aspergillosis, a fungal infection of the lungs that he has battled in the past. However, the cause of death will not be known until after a necropsy has been completed... Alex's veterinarian is returning from vacation to personally conduct this necrospy.'"
